Linux operating system

What is Linux?

The Linux is an open source computer operating system initially developed for Intel x-86 based personal computers.It's been subsequently supported for other hardware platforms. Linux is a freely distributed,cross platform operating system based on Unix that could be installed in Laptops,notebooks,personal computers,mobile devices,tablets,video game consoles,servers,super computers,etc.


From smart phones to super computers,in auto mobiles,home appliances,servers,and everywhere we can find Linux,and these are the gadgets powered by this powerful  operating system. Even though most of the personal computers are powered by Windows operating system( Windows XP,Vista,7,8,or 10), still in security systems,servers,general computers are running by this open source OS. Linux consumes less power,and it takes a while to load. It is said that it doesn't need an antivirus software to protect from viruses,and malware. It has many distributions ( distributions often called as distros),like Ubuntu,Fedora,Kali Linux,Open SUSE,Fedora( Red Hat) and many more. We can install this operating system on our virtual machine( Such as VMware ). It doesn't want much RAM and Hard Disk space to install ( i.e. 1GB RAM 20 GB HDD space).

Kali Linux is one of the distributions of Linux. It has much powerful tools for hacking,such as Footprinting tools,penetrating tools,information gathering tools,social engineering tools and many more.  I believe that a hacker must have knowledge about Linux in order to attack on a website or server or any data base.Linux has GUI ( Graphical User Interface) but,most of the people prefer command line interface,because command line interface is too powerful than GUI. A network administrator must know Linux, we make cluster computers with the help of Linux.
